Yes The coke bottle is on the CofG 2 litres, This has a festo quick release on the feed. A Single Graupner Tank 250cc has two pick ups with sintered bronze clunks , one feeding each motor (if it runs dry both should stop!) I expect to throttle well back and get 8-9 minutes.
The hopper has a quick connect female, the idea being that the hopper can keep fuel in it stopping bubbles getting to the motor.
ECU packs are in the rear of the wheel wells, pumps in the front, ECU's on top of the wing. I made short extension leads to allow the ground unit to be plugged into the fuselage.
I'll post more shots in the morning.
I have my motors well forward, so no lead is needed.
